Application filed September 4, 1918.

To all 107mm t may concern.'

Be it known that I, THOMAS F. DICKIE, a subject of the King of Great Britain, resident of Walkerville, Province of Ontario, Dominion of Canada. have invented certain new and useful Improvements in Locks, of which the following is a specification,

This invention relates to improvements in locks of that type adapted to be used on cloak rooms, lavatories, bathing houses and other places where admission is gained on the payment of a small charge or sum of money, and the objects of the invention are to permit of the lock being actuated on the insertion of a coin of predetermined value, so that admission can be obtained from the yexterior to the room, to provide means whereby the lock may be actuated from the inner side of the room without the use of a coin, to permit of the exit of the user of the room, and to provide means for actuating the lock by means of a key.

Further objects are to facilitate registering the number of coins dropped into the lock, to simplify the construction of the several parts, and generally to adapt the lock to better perform the functions required of them.

Vith the above and other objects in view the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings:

Figure 1 is a perspective view of the improved lock.

Fig. 2 is a rear view of the lock.

F ig. 3 is a vertical section of the lock.

Fig. 4 is a plan view of the back plate of the lock, as seen when removed and showing the mechanism mounted thereon.

Fig. 5 is a plan view of the front of the lock with the back plate removed.

Fig. 6 is a perspective view of the back plate of the lock showing the mechanism mounted thereon.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings A represents the improved lock comprising a casing 10, provided adjacent to its outer edge with an angularly disposed flange 11 which bears against the face of a door.

One of the lateral walls of the casing 10 is provided with a locking bolt slot l2 while Specification of Letters Patent.

Patented Jan. 4, 1921. Serial N0. 252,639.

the upper and lower Walls are provided withy slotted brackets 13, the object of which will be made clear hereafter.

Toward the lower end of the casing a removable door 14 is provided carrying a lock 15 and on removal of the said door access is gained to the casing to remove any money or coins collected therein.

Toward the top of the casing and in the front wall thereof a vertical disposed rectangular oriice 16 is provided and adjacent to this orifice is a vertically disposed rectangular slit 17 through which slit coin may be fed to the lock.

leaf spring 18 is also provided adjacent to the top end of the casing to prevent the back wall rattling when secured in position.

Intermediate of the height of the front wall of the casing is an orifice through which the handle spindle 20 passes, which is provided intermediate of its length with an arcuate tumbler lever 21 designed to` coact with a pin 22 whereby movement of the said lever is limited.

One end of the arcuate lever is 'connected to a spring 23 which is anchored to the vfront wall of the casing, and this lever is further provided with a linger 24 adapted to engage with and retain a coin in position preparatory to rotating the spindle 2O to permit of the arcuate lever engaging the coin to retract the locking bolt as will be eX- plained hereafter.

A key hole 25 is also provided in the casing.

The back wall 26 of the casing is removable and provided with a pair of pivoted rods 27, the hinge pins of which are mounted in slots 28, and these rods are adapted to engage with the slotted brackets 13 at the upper and lower ends of the casing and so hold the back plate in position together with the mechanism mounted thereon.

Intermediate of the height of the back wall 2G a transverse guide way 29 is formed and in alinement with this guide a pair of projections 30 are formed integral with the back wall.

The locking bolt 31 slidably engages with the projections 30 and is provided with lugs 32 which limit the outer motion of the bolt, which is formed with a cylindrical rod 33 connected to a rectangular block 34 which slidably operates in the guide 29.

This block is provided with a vertical slot 35 therein, and the rear wall of the slot eX- tends upwardly above the normal height of the block 34 and provides a flange as shown at 36.

The rod 33 is slidably mounted in the plate or bracket 37 carried by the rear wall 26, and intermediate of this plate or bracket and the locking bolt 31 a spiral spring 38 is located.

Superimpcsed on the block 34 is a bracket 39 provided with a vertically disposed slot 40 which is normally in alinement with the slot 35 in the block 34 and the rear wall forming the slot 40 is cut away to accommo date the flange 36 of the block 34.

The bracket 39 is formed with a boss 41 on which an inverted U lever 42 is pivotally mounted, the said lever having arms of unequal length, the longer arm being oiiset as shown at 43.

On that side of the bracket 39 remote from the boss 41 a second boss 44 is pro vided through which the handle spindle 45 passes, which spindle is rotatable and provided on the inner end with a pair of cam arms 46.

The lever 42 is provided adjacent to the upper end with an offset U shaped arm 47 designed to engage with a crank arm 48 carried by a recording mechanism 49, so that on oscillation of the crank arm 48 the mechanism 49 records the number of times that the lock has been operated by coin means.

A cam lever 50 is pivotally mounted intermediate oi the recording mechanism 49 and the lever 42 and the shorter arm of this cam is adapted to be engaged by the shorter arm of the cam 46,

The back plate 26 is also provided with an ordinary lock 51 actuated by a ke passing through the key hole 25 and w ereby the locking bolt 31 may be retracted by an attendant who desires to enter the room on the door of which the lock is mounted.

When the lock is in use a coin, such as a nickel, is passed through the slot 17 and enters the slot 40 where it drops under gravity into the slot 35.

The coin is retained in the slot 35 by means of the linger 24 of the arcuate tumbler vlever 21, and on rotation of the handle spindle 2O one end of the arcuate tumbler lever 21 engages the face of the coin, so that a force is transmitted to the locking bolt 31 which is thus retracted so permitting the door to be opened.

After entering the room and the door has been closed the locking bolt 31 will under the action of the spring 33 return to its normal position and when the person who has entered the room desires to leave it, he actuates the handle spindle 45 thereby rotating the cam member 46, the longer arm ol? which engages with the block 34 and retracts the locking bolt 31.

During this movement the shorter arm of the cam member 46 engages the shorter arm of the cam lever 50 rotating the same and causing the longer arm of the cam lever 50 to engage with the upper end of the inverted U shaped lever 42 so that the last said lever will be rotated about its pivotal point and the offset arm 47 will rotate the crank member 48 and thus record on the recording mechanism 49, the fact that a coin ias been used to actuate the lock.

From the above description it will be seen that I have invented a lock capable of being utilized on doors of cloak rooms, etc., whereby the lock can be operated by any person desiring to use the room, the lock being such that a denite record of the number of coins dropped into the lock is made.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention within the scope of the claim constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying speciiication and drawing shall be interpreted as illustrative and not in a limiting sense.

vNhat I claim as my invention is:

A lock comprising a casing having a coin slot therein, a locking bolt, guide means coacting with the locking bolt, a rod attached to the locking bolt, a block on the end of the rod having a coin slot therein, a ange on the end of the block adjacent to the coin slot, one of the walls of the slot being cut away to accommodate the flange of the said block, guide means for the block, an inverted Ushaped lever pivoted at the rear of the second said slot and provided with a depending arm coacting with the block, a spring controlling the action of the locking bolt, recording mechanism actuated by the said block, an arcuate tumbler lever mounted beneath the block and provided with a spaced finger terminating below one end of the inverted U-shaped lever and disposed adjacent to the slot in the block to retain a coin in the slot until engaged by the adjacent end of the lever to move the bolt to a retracted position.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
